PUMP.

SPECIFICATION forming part of Letters Patent No. 249,499, dated November 15, 1881.

Application filed August 525, 18H1. (No model.) y

To all whom it may concern Be it known that I, LoUIs BOUVIER, a citi- 'zen ofthe United States, residingat San Diego, in the county of Sau Diego and State of California, have invented certain new and useful Improvements in Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable a vertical transverse section of my improved t pump. Fig. 2 is a vertical longitudinal section ot' the same. Fig. 3 is an end view, with the plate removed from the curved dischargepassages.

In constructing my pump the cylinder A may be supported ou bed-pieces B, or in any other suitable manner. The cylinder has a central supply-opening, a., and a dischargeopening, ct', above which is an air-chamber, G. In the cylinder A is the oscillating piston D, which swings on the central shaft, E, and has two valves, d, Fig. l, the piston and valves being all leather-packed. At the bottom of the cylinder is a radial partition, F, provided with two valves, j', communicating with the supplypassage a, as seen in Fig. 1. The water, after passing from the cylinder A,tlows through pipe G and enters the curved passages H, to be discharged at openings h, Fig. 3. p rIhese curved passages H 4are provided with a double-headed shuttle-valve, I, which is operated by means of curved rod K, which is carried on the radial arm L, attached to the axle or shaft E, and having a ball or weight, M, Fig. 2. The rod K has two guides, k, to steady the motion ofthe rod.

Motion may he given to the pump by means of the swinging lever O or other suit-able de-` vices.

Having described myinvention, what I claim is'- In an oscillating pump having a horizontal cylinder and oscillating piston provided with valves, and also a radial partition havingcheckvalves therein, the water-passage G, in connection with the air-chamber C, in combinationv with the shuttle-valve I, curved passages H, and curved rod K on the swinging radialarni L, having the ball or weight M, substantially in the manner and for the purpose set forth.

LOUIS BOUVIER.
